ZHENG Zhengshuang
( China Classification Society Industry Corporation, Wuhan 430000 )
Abstract: With the increasing attention of the country to environmental protection, as well as the implementation of new energy strategies and energy conservation and emission reduction measures, the construction of LNG fuel powered ships has entered into a period of rapid development.This article briefly introduces the composition of the LNG gas supply system, the structural form of double-walled pipe and the on-site construction technology. This article also summarizes the relevant matters,which need attention in production and installation of the double-wall pipe. Expected to be benefiial to the relevant practitioners.
Key words: ship; LNG fuel; double-walled pipe; welding; tightness test
